For under £50 you can't really go wrong with the Honor Band Zero if all you need is a basic watch with some smartwatch and activity-tracking functionality. With notifications of calls, texts and more, plus basic activity- and sleep tracking, the Zero offers more than the most basic of activity trackers, but less than fully featured smartwatches. If you are going down the Chinese route, this watch isn't quite as good value as the excellend Xiaomi Mi Band 1S Pulse, which also has a heart-rate tracker, but it does have a screen on which to provide notifications.

Aside from sleek looks and a good price, there really isn't much to the Huawei Honor Band Z1. Sure, it's a fine choice if you're looking for an attractive sleep and step tracker, but if you're serious about quantifying your fitness, better options abound. For just $20, the Misfit Flash Link accurately tracks calories, mileage, steps, and even swimming. It can also control music playback on your smartphone and even double as a camera shutter button. If you're willing to spend more, the Fitbit Charge HR tracks more advanced activities like specific workouts, adds heart rate monitoring, has a killer companion app, and supports notifications.
